Abstract

Purpose of review: This paper presents and discusses the most recent research and development on ultrasound applications in minimal processing of fruits, vegetables and other agricultural products

Findings: Ultrasound has great potential to be used either alone or in association with other non-thermal technologies. Areas such sanitisation and washing may highly benefit, since ultrasound enhances the removal of pesticides and also lowers the amount of microorganism on fruits and vegetables.

Directions for future research: Although several studies have shown the effect of ultrasound on plant tissue structure, extraction of many compounds, microorganisms and enzymes, little research has been carried out to show the effect of ultrasound on fruits and vegetables. Further studies are required to explore and evaluate the benefits and restrictions of ultrasound application in minimal processing.
